Estrogen, which is the main enemy of breast cancer patients, is curbed through SERM and AI. Master also shares these characteristics and is capable of preventing estrogen buildup in the body. As DHT derivative, it does not allow aromatization and displays strong anti-aromatase properties. For this reason, Masteron has been used in combination with other drugs to treat breast cancer patients. The role of Masteron then was to block the amount of estrogens in the body while other drugs, such as Tamoxifen-citrate were used to block the binding of estrogen at the breast receptors. Today, many other more powerful aromatase inhibitors have replaced this breast cancer treatment to achieve even greater success in the fight against breast cancer.
As with Masteron Propionate, Masteron Enanthate is well known for being one of the only anabolic steroids that carries strong anti-estrogenic properties. This anabolic steroid cannot increase estrogen levels; in fact, it can actually decrease estrogen levels in the body. It is for this reason Drostanolone was successful in breast cancer treatment with the combination of Drostanolone and Tamoxifen being very commonplace for many years. Bodybuilders welcome this trait due to estrogen often being difficult to control with many steroids and lower estrogen levels often leading to a harder and more defined look during the cutting phase.
Lets look at an example. Your doctor has you on testosterone replacement. You are 45 and have had low test since the age of 40. This condition is very very common. Low testosterone has all sorts of negative health repurcussions. Normal testosterone levels are between 300 and 1100 ng. You want to be at around 1100.. Your doctor wants you around 700-800. To do so he prescribes exogenous test at 180 mgs/week. That amount puts your total test at 760 ng, and your fee test around 10. Adding Masteron increases your free test to 19, Your total test is the same, but your free test, the test you actually use, is much more.
